  • Patent number: 5316179
    Abstract: A system for delivering measured amounts of liquid, such as reagents used in chromatography. Liquid is first moved under gas pressure from a reservoir, such as a reagent bottle, through a valve into a narrow pipe. It reaches a detector which, detecting its presence, closes the valve thus trapping an amount of liquid between the valve and the detector, this amount of liquid then constituting a `unit` or `pulse` of liquid. The movement of the valve is used to connect a gas supply which drives the `unit` or `pulse` out of the pipe to an ultimate destination, such as a chromatographic column. A further `unit` or `pulse` can then be moved into the pipe and this repeated so that delivery to the destination is made in a series of such `units` or `pulse`. By timing the delivery of one `unit` or `pulse`, an amount less than one `unit` or `pulse` can be delivered by passing liquid into the pipe for less than the time taken to deliver one `unit`.

  • Patent number: 4543017
    Abstract: A vortex chamber is disclosed which has a circular elliptical or volute perimeter and end wall. High pressure fluid enters tangentially at the perimeter. Part of this high pressure fluid exits at an axial outlet, forming a vortex. The balance of the high pressure fluid exits at a second tangential outlet at the perimeter. Dry solids are fed into a hopper which is connected to a second axial inlet. The axial inlet should be smaller than the axial outlet, and the two may be concentric. Once the solids enter the vortex chamber, some of them move to the perimeter due to centrifugal force. Once at the perimeter, the solids exit at the tangential outlet.

  • Patent number: 4343574
    Abstract: A customer terminal for a single conveyor tube banking service pneumatic tube system. The terminal has a cabinet which can be opened by unlocking and removing a hinged front member to expose system components and terminal mechanism. The carrier receive and send housing has a hinged door and the housing communicates with the system conveyor tube. The mechanism is operative automatically to present a carrier arriving at the terminal to a customer seated in an adjacent vehicle. The presented carrier is conveniently positioned at an angle at the outer end of a pocket on the door for removal and replacement by a customer without requiring precise positioning. The carrier is returned automatically to the conveyor tube system when replaced in the door pocket. The door has safety mechanism automatically reopening the door if it encounters an obstacle on closing.

  • Patent number: 4334806
    Abstract: An injection system for injecting capsules into a hydraulic capsule pipelining system, the pipelining system comprising a pipeline adapted for flow of a carrier liquid therethrough, and capsules adapted to be transported through the pipeline by the carrier liquid flowing through the pipeline. The injection system comprises a reservoir of carrier liquid, the pipeline extending within the reservoir and extending downstream out of the reservoir, and a magazine in the reservoir for holding capsules in a series, one above another, for injection into the pipeline in the reservoir. The magazine has a lower end in communication with the pipeline in the reservoir for delivery of capsules from the magazine into the pipeline.

  • Patent number: 4284032
    Abstract: A pneumatic conveyor for powdered to granular bulk material, having adjustable conveyance capacity, is disclosed, the capacity being adjusted by electromagnetic adjustment of a pressure regulator disposed in a conduit used to supply a propellant for drawing the bulk material from a storage container thereof and for conveying it. A supplemental supply of gas, which may be but need not be different from the propellant gas, may be provided to control the flow of propellant gas independently of the first pressure regulator. In this case, the flow of the supplemental gas may itself be controlled by a second pressure regulator. The pressure regulators operate according to the diffuser or Venturi principle. The device may be particularly advantageously applied to the spray-coating of articles with a bulk material.

  • Patent number: 4278365
    Abstract: Method and apparatus for controlling sucking of a material suspendible in air or liquid by means of a suction nozzle connected to a pump through a conduit and having a flow rate or solids concentration sensor connected to said conduit, the suction nozzle being supported via a supporting wire rope or like flexible support by a hoisting device which is carried by a device for moving the hoisting device and the nozzle along at least one horizontal axis at adjustable velocity, while the nozzle is vertically adjustably carried by the hoisting device, wherein the hoisting device for vertically adjusting the nozzle is controlled with a control device by signals from the flow rate or solids concentration sensor in such a way that said flow rate or solids concentration sensor is preset to supply a control signal to the hoisting device for raising or lowering the nozzle to thereby restore the flow rate or solids concentration quantity per unit time in the conduit when the flow rate or solids concentration quantity per

  • Patent number: 4157796
    Abstract: A pneumatic tube conveyor dispatcher for converting a pneumatic tube free dispatch system into a pneumatic tube controlled dispatch system. The dispatcher comprises a housing having a rear portion which matingly engages an existing terminal of the free dispatch system such that a carrier storage chamber within the dispatcher housing communicates with the inlet opening of the delivery tube of the free dispatch system. The dispatcher housing includes a door permitting access to the carrier chamber to enable an operator to position a carrier therein. Sensing means associated with the housing chamber senses the presence of the carrier and, in response to a predetermined signal, is operative to actuate a drive mechanism which delivers the carrier through the terminal inlet opening into the pneumatic tube for deployment.
